[Fern]

I’ve got a HP4263A LCR meter which is being used with an ER-18 device to get multiple channel data acquisition, when I go to getting started to trigger the device, but this VI do not have an icon to change the channel how can I insert a code to switch between channels?

I downloaded the drive to look into this for you, but I'm not sure what VIs you are using. Could you provide a sequential list of the VIs you are using to acquire the data? Thanks a lot.

I am just trying to use the drivers developed by NI for this device, but I don't know how to work on them to obtain data from three points, or three channels which I am using from an ER-16 device. So all what I have is the driver VI for the HP4263A.the only VI I can use is getting started, because whe I try to run any other one, this message appears:


Error -1073807346 occurred at VISA Write in HP4263A Self-Test.vi.

Possible reasons:

VISA: (Hex 0xBFFF000E) The given session or object reference is invalid.

your help would be very helpful

thanks
